BINDER FOR LOOSE LEAVES OF BOOKS.

SPECIFICATION forming part of Letters Patent No. 792,389, dated June 13,1905.

Application filed February 4, 1905. Serial No. 244,229.

To nl] urb/0711, it may concern:

Be it known that I, JACOB I). BOEHNER, a citizen of the United States ofAmerica, residing at Freeport, in the county of Stephenson and State ofIllinois, have invented certain new and useful Improvements in Bindersfor Loose Leaves of Books, of which the following is a specification.

My invention relates to a binder designed for holding loose leaves ofpaper of any kind and for any desired purpose in book form until theobject for which they are held together is accomplished, when they maybe readily detached from their holder and have other leavesexpeditiously and conveniently substituted therefor; and it consists ofcertain new and useful features of construction and combinations ofparts especially devised to that end, all as hereinafter fullydescribed, and specifically pointed out in the claims.

Referring to the accompanying drawings, which form a part of thisspecification, Figure l is a section at the dotted line 1 l in Fig. 5through a complete binder, opened, embodying my invention. Fig. 2 is alike View of the same closed. Fig. 3 is a side elevation of the metallicportions ofl the holder with the semirings thereof in the positionsshown in Figs. l and 2. Fig. 4 is a bottom plan View of the parts shownin Fig. 3. Fig. 5 is a section at the dotted line 5 5 in Fig. A of partsthere shown. Fig. 6 is a section at the dotted line 6 6 in Fig. 3,showing one of the semirings thereof locked open to receive leavesthereon. 1

Like letters of reference indicate corresponding parts throughout theseveral views.

A is a fiat, preferably rectangular, backplate having a singlerectilinear corrugation A formed therein along its longitudinal centerand perforated laterally by a plurality of horizontal openings A2,extendingtransversely therethrough and provided with Vertical semiringlocking-notches A3 in their lower edges.

B represents bearing-lugs having bearings B therein and included andseated in the corrugation A in the back-plate A.

O is a longitudinally-slidable rock-shaft included in the corrugation Ain the back-plate A and mounted in the bearings B in the lugs B therein.

D represents semirings corresponding in number with the horizontalopenings A2 in the corrugation A of the back-plate A and rigidly securedby one end Dl of each thereof to the rock-shaft O and projecting'transversely therefrom and parallel to each other through suolihorizontal openings A2 in the corrugation A of the back-plate A andadapted to slide therein and to be rocked therefrom over into and bedetained by their vertical locking-notches A3. E represents semiringscounterparts of and corresponding in number with the semirings D and arefast mounted on the corrugation Al in the plate A parallel to each otherand opposite to such corresponding semirings D when in their normalpositions.

F is a spring coiled about the shaft O and included between one of thelugs B in the back-plate A and one of the semirings D, secured to suchshaft, and normally acting through the latter to maintain the movablesemirings D in operative relation to and engagement with theircounterpart stationary semirings E, as shown in Figs. l and 2 andindicated by dotted lines in Fig. 4.

G represents thin metallic clips secured, preferably by soldering, tothe under side of the plate A, transversely thereto.

H is a thin iiexible strip, preferably of some strong woven fabric, andH is also a thin strip, preferably of some strong fibrous material-as,for instance, tar-board-and is preferably of the same length and widthas the plate A. The strips H H are secured to the plate A, preferably inthe following manner: The points of the clips G are bent at right anglesto the plate A and parallel to each other and then inserted through thefabric H. The strip H next has melted glue applied to its under side andis then placed between the points of the clips G, and the latter arebent inward thereover, as shown in Figs. l and 2.

I represents iiexible covers, to the central portion of which the stripsH H are attached by means of glue.

I' represents the linings of the covers and are pasted thereto.

Ihenever it is desired to place leaves J in the holder, the shaft O isslid endwise until the semirings D are opposite the notches A3 IOO inthe openings A2 in the corrugation A,when such seiniringsD may be roched over thereinto and be thereby locked in the positions shown in Fig. 6and indicated by dotted lines in Fig. 3. The free ends of the semiringsD E are neXt inserted through circular perforations K in the leaves J,and the semirings D are swung out of engagement with the notches A inthe openings A2, and the action of the spring F will then restore thesemirings D to the positions shown in Fig. 4, thereby securing theleaves J operatively in the holder.

Having fully described my invention, what claim as new, and desire tosecure by Letters Patent, is-

l. ln a binder for loose leaves of books, in

combination, a back-plate having a single rectilinear corrugation,formed therein along its longitudinal center, and perforated laterallyby a plurality of horizontal openings extending transverselytherethrough, and provided with vertical semiring locking-notches intheir lower edges, and said corriigations having bearing-lugs includedand seated therein, a longitiidinally-slidable rock-shaft, mounted inthe bearing-lugs within the corrugation in the back-plate, semiringsrigidly secured, by one end of each thereof, to the rock-shaft, andprojecting transversely therefrom and parallel to each other through theopenings in the corrugation of the back-plate, and adapted to slidetherein and to be rocked therefrom over into, and be detained by, thevertical lockingnotches in the lower edges thereof, semirings, thecounterparts of and corresponding in number with thehereinbefore-mentioned semirings and fast mounted, on the corrugation inthe back-plate, parallel to each other and opposite to suchcorresponding semirings, when intheir normal positions, and a springnormally acting, through the longitudinally-slidable rock-shaft, tomaintain the movable semirings in operative relation to and inengagement with their counterpart stationary semirings, substantially asdescribed.

2. In a binder for loose leaves of books, in combination, a back-platehaving a single rectilinear.corrugation, formed therein alongitslongitudinal center, and perforated laterally by a plurality ofhorizontal openings extending transversely therethrough, and providedwith vertical scmiring locking-notches in their lower edges, and saidcorrugations having bearing-lugs included and seated therein, alongitudinally-slidable rock-shaft, mounted in the bearing-lugs withinthe corrugation in the back-plate, semirings rigidly secured, by one endof each thereof, to the rock-shaft, and projecting transverselytherefrom and parallel to each other through the openings in thecorrugation of the back-plate, and adapted to slide therein and to berocked therefrom over into, and be detained by, the verticallocking-notches in the lower edges thereof, semirings, the counterpartsof and corresponding in number with the hereinbefore-mentioned semiringsand fast mounted, on the eorriigation in the back-plate, parallel toeach other and opposite to such corresponding semirings, when in theirnormal positions. and a spring normally acting, through thelongitudinallyslidable rock-shaft, to maintain the movable semirings inoperative relation to and in engagement with their counterpartstationary semirings, clips fast to the under side of the back-plate, aflexible strip, as woven fabric, wider than the back-plate and havingthe clips inserted therethrough, a strip of fibrous material, astar-board, preferably of the same dimensions as the back-plate andclamped, together with the first-mentioned strip and by means of saidclips, fast to the back-plate, and covers connected to the back-plate bymeans of such strips, substantially as described.

3. In a binder for loose leaves of books, in combination, a bach-plate Ahaving a rectilinear corrugation A formed therein along its longitudinalcenter, and perforated by horizontal openings A2 extending transverselytliercth rough, and provided with vertical locking-notches As in theirlower edges, and said corrugation having bearing-lugs B included andseated therein, a loiigitudinally-slidable rock-shaft C mounted in thebearing-lugs B within the corrugation A, semirings D rigidly secured, byone end of each thereof, to such rock-shaft C, and projectingtransversely therefrom through the openings A2 in the corrugation A andadapted to slide therein and to be rocked therefrom over into, and bedetained by, the locking-notches A3 in the lower edges thereof,semirings E, fast mounted on the corrugation A, parallel to each otherand opposite to the semirings D, when in their normal positions, and aspring F normally acting, through the longitudinally slidable rock-shaftC, to maintain the movable semirings D in operative relation to andengagement with their counterpart semirings E, substantially asdescribed.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing witnesses.
